使用 GetProcAddress Function 时,有以下几点需要特别留意: 1. 第二个参数类型是 LPCSTR,不是 ; 2. 用 __declspec(dllexport),按 C 名称修饰(extern "C") 导出的函数名,对于 __stdcall 和 __fastcall 调用约定是相同的;对 __cdecl 是不同的(导出的函数名没有前面的下划线); 3. 即使返回值不是 ...
(fnGetProcAddress)MyGetProcAddress(); std::cout << pfnGetProcAddress << std::endl; // 获取Kernel32核心API地址 fnLoadLibraryA pfnLoadLibraryA = (fnLoadLibraryA)pfnGetProcAddress((HMODULE)kernel32BaseAddress, "LoadLibraryA"); printf("自定义读入LoadLibrary = %x \n", pfnLoadLibraryA); system("pause"...

原理是利用消息钩子将DLL中的代码注入到目标进程中,再用GetProcAddress得到API函数入口地址,将函数入口址改...
hStdout = GetStdHandle(STD_OUTPUT_HANDLE); if(INVALID_HANDLE_VALUE == hStdout) returnEOF; // Write a null-terminated string to the standard output device. while(*lpszMsg != '\0') { fRet = WriteFile(hStdout, lpszMsg, 1, &cchWritten, NULL); ...

int GetPageSource(LPCWSTR szURL,std::string location){ //code... return 1; } using dependency walker on the DLL created from ProjectB, I can see that the function seems to be exported as I am expecting. However, in Project A (where I want to use the function), the following cod...
c++ GetProcAddress()不从dll加载函数我测试代码并得到GetLastError：127 ERROR_PROC_NOT_FOUND：无法找到指定的过程。这意味着不存在具有该名称的导出函数。我建议你应该在Library.h中使用下面的代码：
调用GetProcAddress(...)时，从C++代码调用.NET dll失败从using namespace System;和main的原型开始，我...
typedef HRESULT (STDAPICALLTYPE * LPFNTEST) (void); LPFNTEST _pfnTest; Then I load the DLL:- Code: hDLL = LoadLibrary("MyDLL.dll"); All the above works fine andhDLLgets a non-NULL value . Now I come to obtain the proc address for function “Testâ€:- ...
